Land Anchor With Nested Pull Bar for Mud Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing land anchors are not easily deployable and operable by a single person, lack the strength to extract vehicles from mud or snow, and are not compact enough for storage in vehicles.
Innovation Solution
A portable land anchor system comprising a bucket with an extending blade and a pull bar that can be easily driven into the ground and anchored, allowing a single person to position and operate it, with a winch cable attachment for extracting immobilized vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a land anchor is designed to withstand large forces for extracting vehicles, then the strength and stability are improved, but the device becomes heavier and more difficult for a single person to position and operate
Solution Approach 1:
The land anchor is divided into separate components: a bucket component with blade that provides anchoring strength, and a pull bar component that can be easily handled. This segmentation allows the strong bucket to be driven into the ground for stability while the lighter pull bar with attachment features can be easily manipulated by a single person to connect to the winch cable.
2Volume of moving object
If a land anchor is designed to be compact for storage in vehicles, then the volume is reduced, but the device may lack the necessary strength or functionality to extract vehicles from mud or snow
Solution Approach 1:
The pull bar is designed to nest within or alongside the bucket component when not in use, creating a compact storage configuration that fits easily in vehicle cargo areas. The nested design maintains both the strength of the bucket blade for ground penetration and the functionality of the pull bar for winch cable attachment, without requiring excessive storage space.
3Ease of operation
If a land anchor is designed to be easily driven into the ground, then the ease of operation is improved, but the device may not provide sufficient anchoring stability to withstand extraction forces
Solution Approach 1:
The bucket component is pre-formed with a blade edge optimized for ground penetration, allowing it to be easily driven into the ground by hand or with minimal effort. The blade's geometry is预先 designed to cut through soil, snow, or mud efficiently, while the bucket's overall structure provides the necessary anchoring stability to withstand vehicle extraction forces once positioned.

AI summary
A land anchor is disclosed for pulling an immobilized vehicle out of the mud or snow. The land anchor includes a pull bar which is reversibly connectable or linkable to a bucket by passing the pull bar through a slot in the bucket. The bucket portion of the anchor includes a blade which can be driven into the ground and then removed from the ground once the vehicle has been freed. A connecting end of the pull bar engages the bucket and prevents the pull bar from passing completely through the slot, and can include lateral wings for added strength. The land anchor can be positioned, anchored, and operated by a single person with assistance from a winch and cable assembly to move the immobilized vehicle to a solid area of ground.
